I found an app on android called "Swiftbucks".
You can download apps, answer surveys, complete tasks ( email submits etc. ) and watch passive videos to earn points.
You can redeem them for paypal and bitcoin rewards and the minimum payout is only 1$.
It is one of the highest paying apps I found so far and I earn between 50 cents and 5 dollar a day depending on how much I do.http://bit.ly/yrfeqfg
you can get it here.
If you like the app it would be awesome if you could enter my referrer ID 2045 so that both of us additional rewards.
